Ordering numbers mean arrangement of numbers either from small to big or from big to small.
Della, Victoria, Rachel and Monica are three friends, their heights are (159 cm), (172 cm), (169 cm) and (168 cm) respectively. Can you tell which one is the smallest and which is the tallest?
In order to decide who the tallest girl is, we will have to arrange their heights in a particular order. So, Della (159 cm), Monica (168cm), Rachel (169cm) and Victoria (172cm), with this we get that Della is the shortest. Now, we will find out who is the tallest, by arranging the heights in decreasing order – Victoria (172 cm), Rachel (169 cm), Monica (168 cm) and Della (159 cm) with this we can get that Victoria is the tallest girl.
When we arrange the numbers in an increasing order, it is known as Ascending Order, and when the words are arranged in a decreasing order, and then they are known as Descending Order.
For ascending check the smallest number from the given list and place it first and then put the numbers according to the increasing order.
For descending check the biggest number from the given list and place it first and then put the numbers according to the decreasing order.
Let us take the following examples and arrange them in the given order.
1. 12, 14, 45, 5, 34, 79, 10.
Ascending Order – 5, 10, 12, 14, 34, 45, and 79. Descending Order – 79, 45, 34, 14, 12, 5.
2. 1, 1111, 11, 111. Ascending Order – 1, 11, 111, 1111. Descending Order – 1111, 111, 11, 1.
